    I just received my MBP today and charged it up and am now letting it discharge.
    I have now noticed that the battery health is at 97%.
    Should i be worried??

    No. Battery health can fluctuate. Only start to worry when it drops below 80%.

    It will stay in the mid 90s for quite some time, no need to worry

    Yes, mine went from 97% to 101% after calibrating the battery. Even at 97% it was estimating 7+ hours with light usage so I wasn't complaining.

    hey I have the reason for this, bought a brand new 2011 mbp top of the line blah blah blah and had the same thing happen to me so I took it into the store and they couldn't give me a reason and in fact one of the guys told me this is normal that it was a software coding issues. All of this is wrong and through a bit of research I found this was due to a recent change they made in the MBP's to "give the batteries a greater longevity" meaning that sometimes the newer computers consume a slight bit more than the charger is currently giving it as apparently the chargers fluctuate in power much the way your home does so it drops a percent or two. The part that has apparently changed to help batteries is that the mbp won't start to recharge until it drop below 95 percent I believe it was. All of this is posted somewhere in some update release info and I wish I could provide you the link but no longer know where I read this information at. There is no problem with the battery as a way you can prove this is unplug the computer and let it drop down to low 90's then plug it back in and it should charge all the way to 100 percent. hope this has helped :) good luck, joined the forum just to try and help and this drove me crazy the first month I owned the computer as I kept thinking I should take it back.

    You're confusing the reading for battery health, which is what this thread is about, and current battery charge. It's not a software coding issue and it doesn't have anything to do with the newer batteries having greater longevity. To clear up the confusion, click the link below and read. This should answer most, if not all, of your battery questions:
